Our Skillful Manufacture Laser Welded Finned Tube / Stainless Steel Finned Pipe, a top-notch heat exchanger solution designed for optimal performance. Crafted with precision and state-of-the-art technology, it promises unrivaled thermal efficiency. Crafted with precision and expertise, this product guarantees efficient heat transfer and cooling capabilities. Experience a new standard in energy conservation and performance stability.
The fins (solid or serrated) are helically wound and continuously welded to the tube by a fully automatic laser finning machine, ensuring a seamless integration and exceptional durability. This innovative laser finning process produces a perfect fin-to-tube bond with minimal heat input, enhancing thermal conductivity and resistance to corrosion.
Advantage
The advantages over conventional MAG/HF welding are of decisive importance, offering breakthroughs in efficiency and durability.
The complete connection between the fins and the base tube brings about excellent heat transfer and up to 2.5 times higher thermal performance of the finned tubes, setting a new benchmark for thermal management.
The continuous weld prevents notch effects and corrosion; cracks are hence avoided even under conditions of oscillation in finned tubes.
The low base metal heating during welding and the high speed of travel, up to 20m/min, significantly minimize the heat-affected zone in the base tube, preserving the integrity of the material. Complete melting of the tube and a related metallurgical transformation of the parent metals are hence excluded, ensuring structural stability and longevity.
Description
· Thin, continuous weld seam for optimal strength
· Small heat-affected zone, maintaining material integrity
· Only slight discoloration at the weld site, preserving aesthetics
· Only slight microstructural change in tube and fin, ensuring performance consistency
· High utilization of heat for forming the seam, maximizing energy efficiency
· Increased safety due to avoidance of crevice corrosion, thanks to high weld integrity between tube and fin
· No impurity of the weld seam, as Laser-welding is carried out under a protective atmosphere, guaranteeing purity and quality
